Water and Wastewater Program 2009
Irrigation Outline

Background Info & Terminology
– Main Irrigation Types

Level Sensing/Soil Moisture

Switch/Valve Actuation

Flow Meter/Pressure
Key Terms and Background Info

Irrigation is the application of water to assist
in growing crops in dry areas and during
periods of inadequate rainfall

Irrigation is also used to protect plants from
frost, prevent weed growth in rice fields and
to prevent soil compaction

Irrigation Types
– Surface Irrigation
– Localized Irrigation
– Sprinkler Irrigation
Irrigation Types

Surface Irrigation is a system where water
moves over and across the land by the use of
simple gravity in furrows, border strips, or
basins

Localized Irrigation is a system where water is
distributed through a pipe network and
applied as a small drip or discharge near each
plant

Sprinkler Irrigation is a system where water is
piped to one or more locations in a field and
distributed through high-pressure sprinklers or
sprayers
Surface Irrigation Level Sensing

Irrigation District controls the flow volume in
channels based on daily demand of water

Ultrasonic sensor utilized to measure water level
– Sensor provides a 4 – 20 mA signal at Node

Information transmitted to control room
– Gateway output provides 4 – 20 mA signal
– Digital panel meter displays scaled flow volume
– Operator manually turns pumps On/Off as
required to maintain correct water level


Moisture Sensors are used to monitor the soil
moisture (SDI-12 Irrigation Standard)

Banner offers a number of FlexPower Nodes to work
with the SDI-12 standard (contact Banner)

This information is used to help determine the
correct level of water in the border strips
Localized Irrigation System in Orchard

The orchard uses a drip irrigation system and has 200
vaults

Each vault has a Siemens Mag flow meter
– Each flow meter will need a DX80 Counter Node
– 4 DX80 Gateways for wireless network
– Gateways mounted in a truck that drives through
orchard

Totalized outputs from the DX80 Counter Node
determine water consumption
– Data will be written to a flash drive as the truck
tours the orchard

Localized Irrigation Challenges

Irrigation systems can cover large areas of
2-3 km or more

Must transmit signals over hills
– Requires antenna extensions
– Requires correct network geometry

Use Data Radios for range extension

Many of these locations do not have power
available
– These applications require battery and solar
power solutions

Localized Irrigation Other Applications

Valve/Switch Control
– Use Node discrete outputs
Localized Irrigation Other Applications

Soil Moisture Monitoring
Sprinkler Irrigation

Used in large scale agricultural operations

Two main types of sprinklers
– Pivot
– Lateral
Sprinkler Irrigation Applications

Flow Meter

Pressure Monitor

Sprinkler Position Control

Soil Moisture

These applications ensure consistent watering
Solar Power for Irrigation

Due to the large scale of many irrigation systems,
power is not always available

Banner Solar Panel BWA-SOLAR-001 can provide
the power required
– Nodes available for continuous power

Other Solar Power systems can also be used
